I'm not feeling the screens, or the idea of a prequel. Putting a whole exposition on Rachel and the past feels heavy handed and unnecessary. The comparison to Twin Peaks is apt - not every story thread needs a proper exposition.
Exactly this.
If they're going to blown Rachel's importance out of proportion and turn her into a starting point of it all, I'll be extremely disappointed.
However, if they're just going for a somber look into how their friendship and relationship started, I'm up for that, but don't see the gameplay or story hook in that.
